General Issues

The DRS can be operated in two different ways:
  • You can use it via web interface. This provides the possibility of managing the applications interactively.
  • On the other hand it is possible to complete e-mail forms and send them to our robot. This method can be used for the registration of new domains, registrar transfers with Knipp as gaining registrar, for the modification of domain data and for the deletion of a domain.
You can use both methods to modify your stock of domains. In order be able to always keep your own database up-to-date, our robot sends responses in either case, if modifications to your data are to be expected. A typical case is the registration of a new domain, but it may also be a deletion or any other type of modification.

E-mail application forms

Professional users can initiate domain processings via e-mail application form. There is a specific form available for each domain type, and for each of these forms we provide detailed instructions on how to fill in the fields.
Please send your completed application forms to Only the domain types that are listed in the table below can be can be processed in a fully automated way send by sending forms to the above mentioned e-mail address.

  • Accounting and finance
In this table you can see which employee of your company receives which kind of e-mails.
Please inform our support team if you want any changes of your actual profile.

DRS robot

All DRS robot responses are encoded as Content-Type: multipart/mixed in MIME standard. This has the advantage that you can »pick« only those parts that are relevant for your actual task and ignore the other parts.
Based on our usage of the MIME standard you can use a multiplicity of existing libraries for different programming languages and access the different parts of the responses by using a few lines of code. Favored programming languages for this purpose are Perl, PHP and Java. To give only one example, the MIME::Tools of Perl located in the CPAN Library can be cited.
The responses are divided into the following MIME sections. Some sections include subsection. The 3rd section is optional.
Textual description of the DRS robots' response.
This part explains the result of the request in human-readable format. The balancing act between expressing the issue understandingly for the laymen without boring professionals is attempted.
(Please also pay attention to the remarks below.)
Response in ASCII format
This part is adequate for text-based e-mail clients, which use a non-proportional font, as for example PINE, ELM, or MUTT.
It is being attempted to display tables by using spaces and hyphens.
See the example below.
(Please also pay attention to the remarks below.)
Response in HTML format
Usable for e-mail clients, which can handle HTML. Tables are displayed as graphical elements. Important text parts are displayed in semi-bold font, logos and pictures are used as indicators for particularities.
(Please also pay attention to the remarks below.)
Robot response
This part is designed for automated processing, particularly by scripts or other robots.
The responses always consist of key-value pairs, with one pair on every line. A colon separates keys from the values.
In the overview you can see what key-value pairs exist and in which situations they are being used.
See the example below.
If you have sent an e-mail application form to the DRS, it is included in this part. This simplifies the analysis of possible errors, which are listed in the robot part.
Application in ASCII format
Your original application in ASCII format.
Remark: If the sending of HTML e-mails is deactivated in your profile, only the ASCII variant is used in section 1. The deactivation can be accomplished on your request by our support team.
